We’ve all heard the classic investing mantra: “Buy good stocks and hold them forever.” It sounds perfect, doesn’t it? Set it and forget it. But as a business owner who has weathered a decade of market cycles—from booms to sudden crashes—I’ve learned that the real world is rarely that simple.
If you bought major tech stocks at the peak of the dot-com bubble, or high-growth stocks at their 2021 highs, you didn’t just “hold.” You endured years of waiting while your portfolio value eroded. If you had no strategy other than “hope,” you likely suffered incredible emotional stress.
For me, long-term investing isn’t about being passive. It’s about active risk management. Over time, I’ve developed a rule that fits my personality and keeps me from losing sleep: The 10% Safety Valve.
My 10% “Safety Valve” Strategy
I don’t try to time the absolute top or bottom. I’m not a professional day trader, and I have a business to run. Instead, I use a simple, rule-based approach that helps me maintain discipline. I treat my portfolio like a business balance sheet:
- The Exit (The -10% Rule): If a stock or asset drops 10% from its recent peak, I trim my position. This isn’t about panic selling; it’s about capital preservation. It acts as a “circuit breaker.” By trimming, I force myself to step back, re-evaluate the company’s fundamentals, and lower my exposure if the trend has truly turned against me.
- The Re-entry (The +10% Recovery Rule): If the stock finds a bottom and starts to recover—gaining 10% from its recent low—I consider adding back. This is my signal that the momentum has shifted and the “danger zone” has passed.
This isn’t about being “right” every single time. It’s about ensuring that if I am wrong, I am wrong small, and if I am right, I am right big.
Is This a Perfect System?
To be honest: No. It doesn’t always catch the perfect price. Sometimes the market “whipsaws”—I might sell only to see it bounce back, or buy back just before another dip.
But here is the key: It fits my psychology. As a business owner, I value control. When I operate my business, I look at KPIs, profit margins, and overhead. Why should I leave my retirement accounts to “blind luck”? This rule helps me stay disciplined, prevents emotional decision-making, and keeps my portfolio aligned with my risk tolerance. It prevents me from “staying wrong for too long.”
Investing is Like Running a Business
Think about your business operations. If your company’s sales dropped 10% for the quarter, you wouldn’t just “hope” it gets better. You would analyze the situation, cut costs, pivot your strategy, and reallocate resources.
Why should your portfolio be any different?
Don’t let “long-term investing” become an excuse for negligence. You are the CEO of your own wealth. When you adopt the “CEO Mindset,” you stop being a victim of market volatility and start being an architect of your financial outcomes.
Practical Steps to Implement Your Own Rules
If you want to move beyond “passive holding,” consider these three steps:
- Define Your Thresholds: 10% might be too aggressive or too conservative for your portfolio. Maybe your “business logic” dictates 15% or 20%. Choose a number that makes you feel in control, not one that makes you panic-trade.
- Automate Your Watchlist: Use brokerage alerts to notify you when an asset hits a certain percentage drop. You don’t need to stare at the screen; let the tech work for you.
- Review Fundamentals, Not Just Prices: When you sell on a -10% rule, ask yourself: “Has the business changed, or just the price?” If the business is still solid, you might buy it back at a discount. If the business fundamentals have broken, you’ve protected your capital from a long-term decline.
Frequently Asked Questions (FAQ)
Q: Doesn’t this create a lot of taxable events? A: That is a fair concern. This is why I execute this strategy primarily within my tax-advantaged accounts (like my Roth IRA). Inside these accounts, I can rebalance and “trim” without immediate tax consequences.
Q: How do I manage this for a 17-year horizon? A: The rule is meant to protect your principal while you build. As you get closer to your goal of age 67, you might tighten these rules to protect your wealth even more aggressively.
Q: Is this “Market Timing”? A: Some might call it that, but I call it “Risk Management.” There is a difference between guessing where the market will go tomorrow and having a plan for when it moves against you.
